Top priority is finishing the OOJS handling -- this has to be done and cleared as soon as we can, to remove blocks for other work.
Also, Dan G asked for us to help with UserMerge support for Flow -- it's required for SUL, and Dan & Kunal need our help. There's a card at the top of the Sprint J column. Sorry for adding something else to the sprint, but if we can pick it up, it'll help them out.
Erik:
Found a bug in one of Matthias' patches required a change
to core parsing for wikilinks.
Worked on placement of anon warning in preview (bug 71283), in code review.
